The natural history of prenatally diagnosed congenital pulmonary airway malformations and bronchopulmonary sequestrations

Topic overview

Study of 66 prenatally diagnosed CPAM/BPS cases shows 56% regress during gestation and 69% can be managed conservatively. Mediastinal shift, high CVR, and large lesion size predict need for surgery. Most asymptomatic newborns remain symptom-free through childhood with watchful waiting approach.

Key takeaways

56% of prenatally diagnosed CPAM/BPS lesions decreased in size during gestation, with 94% overall survival rate.
69% of cases managed conservatively with median 4-year follow-up; only 19% developed symptoms after neonatal period.
High CVR, mediastinal shift on postnatal imaging, and large gestational lesion size predict need for surgery.
Asymptomatic infants beyond neonatal period typically remain symptom-free throughout childhood with watchful waiting.
Prenatal regression is common; conservative management is safe for most prenatally diagnosed CPAM/BPS cases.
